5.4.2
Concentration with continuous run
Use the continuous run function if you do not want to set a fixed run time.
1. Using the time arrow keys, set the continuous run, (oo) can be achieved below 0:01 or above
9:59.
2. Set all other parameters as previously described (see Concentration with time setting on
3. Press start/stop to start concentration.
Time counting is upwards in minute increments.
4. Press start/stop to stop the concentration after the required time.
5. The subsequent procedure and process is the same as for concentration with time setting.
5.4.3
Overrun phase
1. After completing the work, let the device run on with the empty rotor for at least one minute.
2. Press the mode/vent key for a few seconds to remove any residual condensate from the
pump.
5.4.4
Removing the rotor and switching off the device
1. If required, switch off the heating.
2. Remove the rotor.
3. Wipe up any liquid that has been spilled in the rotor chamber and on the device lid, using an
absorbent cloth.
4. Clean the rotor chamber and device lid, as described separately (see Perform cleaning/
5. Leave the device lid open and secure it against falling shut to let any remaining residual liquid
evaporate.
6. Switch off the device at the main switch.
Hint!
During the run you can:
•
Change the total run time. The new parameters are adopted immediately. Be aware that the
shortest new total run time which can be set is the time which has already elapsed plus 2
minutes.
•
Adjust the setting of the brake function and the temperature.
•
Ventilate the rotor chamber manually by holding the mode/vent key. In this way, condensate
can be removed from the device lid and the pump and the hose system rinsed.
•
Check by means of a stroboscope how far the concentration has progressed.
•
Stop concentration before the set run time has elapsed. To do this, press the start/stop key.
CAUTION!
Caution! Continuous delivery can affect safe operation of the device.
When delivering liquids continuously, membranes and valves of the vacuum pump can be
damaged.
Only use the device for applications of limited duration.
Hint!
If the device runs longer than 9:59 h, 9:59 remains on the display.
Hint!
Rotor A-2-VC: Remove the buckets first before holding the rotor at the rotor cross, using both
hands to lift it out of the device.
